How does the concept of 'birth and death' apply to avatars like Sai Baba, according to the text?

Chapter 43 elaborates that for avatars like Sai Baba, birth and death are considered 'false imaginations.' The text posits that the union of body and senses is birth, and their separation is death. However, for a being who is the complete Supreme Brahman, beyond bodily impulses, these concepts do not truly apply. As stated in Chapter 43, saints incarnate by their own will with the sole desire for the welfare of devotees. Since they have already conquered death, placing their 'feet on the head of Time,' the cycle of birth and death does not touch them.
